Fig. 4: Performance of photoanodes in non-aqueous electrolyte.

a Cyclic voltammogram of THIQ with platinum mesh as working electrode. b Current density of DCN electrodes under different synthesis conditions: polymer type and concentration, and temperature, at +0.22 V vs. Fc+/Fc (see Table S3). c Transient photocurrent density response of DCN and CN electrodes at +0.22 V vs. Fc+/Fc. All experiments were performed using 0.1 M LiClO4 in methanol. Source data are provided as a source data file.
